Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

Creator:

Gatimu, Kevin

Abstract:

The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

Creator:

Johnson, Taylor N.

Abstract:

Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

Offloading of I/O transactions in current CPU architectures

Creator:

Larsen, Steen K.

Abstract:

IO transactions within a computer system have evolved along with other system components (i.e., CPU, memory, video) from programmed IO (PIO). In current mainstream systems (spanning from HPC to mobile) the IO transactions are CPU-centric descriptor-based DMA transactions. The key benefit is that slower IO devices can DMA write system...

Dissertation
The dynamic speculation and performance prediction of parallel loops

Creator:

Zier, David A.

Abstract:

General purpose computer systems have seen increased performance potential through the parallel processing capabilities of multicore processors. Yet this potential performance can only be attained through parallel applications, thus forcing software developers to rethink how everyday applications are designed. The most readily form of Thread Level Parallelism (TLP) within any...
